Textract vs Document AI vs Azure Document Intelligence for invoices
Compares the major cloud document AI services for invoice extraction to choose one. Use when selecting an extraction engine. Not for implementation details of any single service.
TL;DR
All three cloud services extract invoices well; the choice comes down to your stack and needs. Textract fits AWS shops and pairs with Comprehend; Document AI has strong pretrained invoice processors and fits Google Cloud; Azure Document Intelligence fits Microsoft shops with good layout models. Evaluate on your own invoices: run a labeled sample through each and compare field-level F1 on line items, not just headers, plus cost per page at your volume.
Steps
- Assemble a labeled sample of 50-100 of your real invoices, including ugly scans.
Expected: A representative benchmark set.
- Run each candidate service and score field-level precision/recall, weighted toward line items.
Expected: Comparable accuracy numbers.
- Measure cost per page at your monthly volume, including reprocessing.
Expected: True operating cost.
- Check data residency and compliance needs against each vendor.
Expected: A shortlist that passes legal.
- Pilot the winner on one vendor or entity before full rollout.
Expected: Production proof before commitment.
When to use
- Selecting an invoice extraction engine
- Replacing template-based OCR
- Cloud vendor decision for AP
When not to use
- Open-source-only requirements
- On-premise constraints
- Single-service implementation guides
Compatibility
AWS Textract, Google Cloud Document AI, Azure AI Document Intelligence. All offer pretrained invoice models.

Root cause
Vendors publish headline accuracy on clean benchmarks, but real AP accuracy depends on your invoice mix: scan quality, languages, table complexity. Only a benchmark on your own documents predicts your results.
Edge cases
- Open models (PaddleOCR-VL, DeepSeek-OCR) now rival cloud APIs on parsing; include one in the eval
- E-invoice XML (Factur-X/ZUGFeRD) bypasses OCR entirely where available
- Price changes with volume tiers; model your growth, not just today
